You can use sequence-item of course, but sequence-item is a little bit 
tricky, if you want to use it in python-expression because of the minus 
sign (means subtraction in python). You have to use something magic like 
_['sequence-item'] to work with it this way. "Prefixing" with 
prefix=list "renames" 'sequence-item' to 'list_item', which you can use 
normally in python-expressions.
